I forgot the iPhone passcode!Three ways to help with resetting, 2021 version

　The iPhone is equipped with a "Touch ID" (fingerprint authentication) and "Face ID" (face authentication) as a mechanism for authenticating the user, so the opportunity to enter passcodes has decreased more than before.However, if those authentication fail, you need a passcode after restarting your iPhone.

　If you forget the passcode, there is no other way but to initialize the main unit and reset it.If you do not have a backup, be aware that even if you can reset the pass code, it will not be restored to the original state.However, if the situation applies, it may be possible to initialize after taking a backup.

　In 2018, an article summarizes how to deal with the iPhone passcode.However, the specifications were changed, and some scenes did not fit in the current situation.

　Therefore, this time, as of June 2021, I will introduce how to reset the latest passcode.

目次●第1の方法：パスコードを10回間違える●第2の方法：「リカバリーモード」で初期化●第3の方法：「探す」機能を使う裏技●早めにバックアップを取っておこう●お勧めはリカバリーモードによる初期化

第1の方法：パスコードを10回間違える

　The first method of initializing the iPhone and resetting the passcode is that the passcode input is mistaken 10 times.

　If you make a mistake in the passcode input five times in a row when restarting the iPhone, etc., it will be called "Lockout", and the screen will be displayed as "Please start over one minute later."If it fails for the sixth time, the next will be "Please start over 5 minutes."

　If you fail seven or eight times, the waiting time will be 15 minutes for the next time you can enter.If you make a mistake in the ninth time, you will not be able to re -enter the passcode unless you wait an hour.

　At this point, the possibility of remembering the correct passcode is quite low.What happens if I keep entering the passcode as it is?

　If "Settings" on the iPhone → "Touch ID and Passcode" or "Face ID and Passcode" is turned on on the displayed screen, "Erase Data" is turned on 10 times.If it fails continuously, the data on the terminal will be completely erased.The passcode can be reset after restarting.This is the first method.The specific resetting procedure is the same flow as the second method described later, "Initialization of iPhone in" Recovery Mode "".

　In fact, this time, when I actually tried it, even if I failed 10 times, it was not erased, and it was actually erased at the time of the eleventh time I waited for another hour.

　However, the setting screen states that "if you fail 10 times, erase it", so it was explained here as 10 times.In the unlikely event that the actual specification is 11 times, the data will not be erased immediately.

　It is an unrealistic method that takes too much time, but it is introduced as the first method to explain what happens if you keep making a mistake in the passcode.

　In order to use this method, it is necessary to turn on data, but the item "Erase Data" is on "Settings" → "Touch ID and Passcode" or "Face ID and Passcode" screen.Yes, you need a passcode to enter this screen.

　Therefore, if you do not know the passcode, you have to enter the passcode 10 times and try to fail.However, since it is off in iOS default settings, it is highly likely that if you have not changed in the past, it will be off.

　If "Erase Data" is off, the iPhone will be completely locked if the passcode input fails in the 10th time.In this case, the iPhone alone cannot be initialized.You need a computer with "iTunes" installed.Here are the following methods.
